[texts]Assessment of Power System Stability by UPFC with Two Shunt Voltage-Source Converters and a Series Capacitor
In this paper, the effects of a newly presented structure of unified power flow controller (UPFC) which is based on two shunt voltage-source converters and a series capacitor, are investigated on the dynamic stability of power system. A power system including the newly presented structure of UPFC is introduced to examine this. The non-linear dynamic model of the system under investigation and its non-linear equations are presented as well...

[texts]Turning the Moon into a Solar Photovoltaic Paradise - Freundlich, Alex
Lunar resource utilization has focused principally on the extraction of oxygen from the lunar regolith. A number of schemes have been proposed for oxygen extraction from Ilmenite and Anorthite. Serendipitously, these schemes have as their by-products (or more directly as their ''waste products''), materials needed for the fabrication of thin film silicon solar cells. Thus lunar surface possesses both the elemental components needed for the fabrication of silicon solar cells and a vacuum environm...

[texts]The Use of Heavy Gas for Increased Reynolds Numbers in Transonic Wind Tunnels - Anders, J. B.
The use of a high molecular weight test gas to increase the Reynolds number range of transonic wind tunnels is explored. Modifications to a small transonic wind tunnel are described and the real gas properties of the example heavy gas (sulfur hexafluoride) are discussed. Sulfur hexafluoride is shown to increase the test Reynolds number by a factor of more than 2 over air at the same Mach number. Experimental and computational pressure distributions on an advanced supercritical airfoil configurat...

[texts]Non-Linear Structural Dynamics Characterization using a Scanning Laser Vibrometer - Pai, P. F.
This paper presents the use of a scanning laser vibrometer and a signal decomposition method to characterize non-linear dynamics of highly flexible structures. A Polytec PI PSV-200 scanning laser vibrometer is used to measure transverse velocities of points on a structure subjected to a harmonic excitation. Velocity profiles at different times are constructed using the measured velocities, and then each velocity profile is decomposed using the first four linear mode shapes and a least-squares cu...

[texts]Some experiments with coupled high-frequency circuits (Volume Bulletin of the Bureau of Standards, Vol. 7, 301-314 (1911) Scientific Paper 158 (S158))
The relation between the energy of oscillation in two coupled circuits and the coefficient of coupling is investigated. The primary aircraft is excited by means of a vibrator worked by an electromagnet, and this circuit excites the two coupled circuits under observation. The arrangement is taken as representing a sender and a receiving circuit with a detector circuit coupled to it. It is the energy relations in the last two which are studied...

[texts]A Precision Metrology System for the Hubble Space Telescope Wide Field Camera 3 Instrument - Toland, Ronald W
The Wide Field Camera 3 (WFC3) instrument for the Hubble Space Telescope (HST) will replace the current Wide Field and Planetary Camera 2 (WFPC2). By providing higher throughput and sensitivity than WFPC2, and operating from the near-IR to the near-UV, WFC3 will once again bring the performance of HST above that from ground-based observatories. Crucial to the integration of the WFC3 optical bench is a pair of 2-axis cathetometers used to view targets which cannot be seen by other means when the ...

Measurements using silicon detectors to characterize the radiation transmitted through the EMU space suit and a human phantom have been performed using 155 and 250 MeV proton beams at LLUMC. The beams simulate radiation encountered in space, where trapped protons having kinetic energies on the order of 100 MeV are copious. Protons with 100 MeV kinetic energy and above can penetrate many centimeters of water or other light materials, so that astronauts exposed to such energetic particles will rec...

[texts]Synergy of Particle Swarm Optimization and Bacterial Foraging for SSSC Damping Controller Design
Social foraging behaviour of Escherichia coli bacteria has recently been explored to develop a novel algorithm for optimization and control. One of the major driving forces of Bacterial Foraging Optimization Algorithm (BFOA) is the chemotactic movement of a virtual bacterium that models a trial solution of the optimization problem. However, during the process of chemotaxis, the BFOA depends on random search directions which may lead to delay in reaching the global solution...

[texts]Human Physiological Responses to Cycle Ergometer Leg Exercise During Gz Acceleration - Chou, J. L.
Spaceflight and bed-rest deconditioning decrease maximal oxygen uptake (aerobic power), strength, endurance capacity, and orthostatic tolerance. In addition to extensive use of muscular exercise conditioning as a countermeasure for the reduction in aerobic power (VO(sub 2max)), stimuli from some form of Gz acceleration conditioning may be necessary to attenuate the orthostatic intolerance component of this deconditioning...
